The best way to understand that is to break it down.

1. The following should be obvious. All I did was to take out src url.

<img src='……' align="left" height="50" class='imageborder' border='0'>

    Here’s the src url

            <@ofbizContentUrl>${requestAttributes.contentPathPrefix?if_exists}${managerSpecial.smallImageUrl?default("/images/defaultImage.jpg")}</@ofbizContentUrl>

2. Src url has the following form

            <@ofbizContentUrl>…..</@ofbizContentUrl>

    This is specifying that it is a content url and the prefix is defined in a file (I don’t remember the name but you can search on this mailing list, it was stated recently).

3. The remaining part is this

            ${requestAttributes.contentPathPrefix?if_exists}${managerSpecial.smallImageUrl?default("/images/defaultImage.jpg")}

    It is made up of two freemarker expressions each enclosed in ${…}

4. ${requestAttributes.contentPathPrefix?if_exists} is evaluated to the requestAttributes.contentPathPrefix if it exists, “” String otherwise.

5.  ${managerSpecial.smallImageUrl?default("/images/defaultImage.jpg")} is evaluated to managerSpecial.smallImageUrl if it exists, "/images/defaultImage.jpg" otherwise.
